Abstract

The invention relates to a device for automatically detecting the content of methane H2S in a laboratory. The device comprises a structure setting cavity, a wheel disc, a wheel disc motor, a peristaltic pump for quantitatively, regularly and uniformly pumping gas, an electromagnetic needle and a control structure. The invention is characterized in that the wheel disc is arranged above the structure setting cavity, and the wheel disc motor is arranged on the inner side above the structure setting cavity; the peristaltic pump is arranged on the inner side of the other side surface of the structure setting cavity, and an extraction pipe and an exhaust pipe are arranged on the peristaltic pump; the exhaust pipe above the peristaltic pump is connected with the electromagnetic needle; the exhaust pipe of the peristaltic pump is connected with a laboratory methane main pipe; the wheel disc comprises a main disc and a connector; the peristaltic pump, a turntable motor and the electromagnetic needle are all connected with a control structure; the control structure controls and sets the air pumping speed and the air pumping amount of the peristaltic pump, the rotating angle of the turntablemotor and the power-on and power-off of the electromagnetic needle, and the control structure controls the operation of each part to realize the detection of the content of the methane H2S in 24 hours.

Description

technical field [0001] The invention belongs to the technical field of biogas desulfurization, in particular to a laboratory automatic detection of biogas H 2 The device and detection method of S content. Background technique [0002] Conventional laboratory biogas H 2 The S detection method is that the experimenters regularly sample the biogas according to the experimental requirements, and pass the biogas in the gas sampler into the H at a uniform speed. 2 S gas detection tube, H 2 S reacts with the indicator gel to produce a brown color-changing column, and the data is read out through the height of the color-changing column. [0003] Biogas H under existing experimental conditions 2 The S detection method relies on manual operation, which is inefficient and time-consuming; there is human interference in the operation process of the uniform injection of the sampler, which is prone to errors; unattended long-term multi-batch detection cannot be realized, because the 24...
